This upholstery stapler is a game-changer for industrial and scientific settings. As my tests showed the 20 gauge nails are perfect for securely attaching fabric to hard materials .The ergonomic design makes it easy and comfortable to use for extended periods of time. However, the only downside is that it requires an air compressor to operate, which may limit its portability. Overall, a reliable and efficient tool for any professional in need of quality results..
